Abstract (en)

[origin: WO2015077964A1] Methods, apparatuses and a user equipment for performing a Hybrid Automatic Repeat Request (HARQ) transmission in a downlink from a base station to at least one user equipment are provided. An exemplary method comprises receiving a HARQ feedback to a HARQ transmission performed with respect to a transport block. The method further comprises determining whether the HARQ feedback is an ambiguous HARQ feedback with respect to a negative acknowledgement or a discontinuous transmission. The method additionally comprises setting (S206) the ambiguous HARQ feedback as the negative acknowledgement or the discontinuous transmission based on the number of HARQ transmissions having been performed and the corresponding received HARQ feedbacks within a target number of HARQ transmissions counting from a first HARQ transmission. With the methods and apparatuses, the ambiguity of the HARQ feedback can be overcome and communication efficiency may be improved.
